MFC r336582:

makefs(8): add test case for PR 229929

Fix two failing makefs test cases by adding "-M 1m", which was already used
for every other FFS test case. Add a new test case for the underlying
issue: with no -M, -m, or -s options, makefs can underestimate image size.

MFC r320163:

Fix usr.sbin/makefs/makefs_ffs_tests when /etc/fstab does not exist

dumpfs prints a harmless warning message (via ufs_disk_fillout(3) and
getfsfile(3)), when /etc/fstab does not exist. We can ignore it.

Clean up mtree keyword support a slight bit and add a few more default keywords

- Parameterize the mtree keywords as $DEFAULT_MTREE_KEYWORDS
- Test with the extra mtree keywords, `mode,gid,uid`.
- Add a note about mtrees with time support not working with makefs right now

Add more cd9660/FFS makefs testcases

General changes:
- Parameterize out the mount command.
- Use mtree to verify the contents of an image (check_image_contents) instead
of using diff (diff verifies content, but not file metadata).
- Move common logic out to functions (common_cleanup, mount_image,
check_image_contents)
- Add stub testcases for makefs -D (crashes with SIGBUS, similar to bug # 192839)
- Add a note about the ISO-9660 and rockridge specs
- Add testcases that exercise:
-- Creating disk images from an mtree and multiple directories.
-- -F flag use (not really an extensive testcase right now)

cd9660-specific test changes:

- Remove an XXX comment about symlinks; I forgot that non-rockridge images turn
symlinks into hardlinks.
- Add testcases that exercise:
-- -o allow-deep-trees
-- -o allow-max-name stub testcase (doesn't seem to be implemented in makefs)
-- -o preparer (existence in image; not conformance to spec)
-- -o publisher (existence in image; not conformance to spec)
-- -o rockridge (basic)

Revise "create_test_inputs" to simplify the file structure as
these testcases don't need to be nested as much as bin/ls/ls_tests.sh
do when verifying ls -a, ls -A, etc. This allows the tests to make
all paths relative to the top of the temporary directory instead of
always tacking on $ATF_TMPDIR, thus complicating things unnecessarily

Create non-empty files in create_test_inputs as well now, similar to
create_test_inputs2 in bin/ls/ls_tests.sh

Compare the input files to the output file contents using diff where
possible:
- Skip over the fifo comparison for now because it always fails
- Skip over the symlink comparison on cd9660 because it always fails
today
